While Billie is still currently starring on the ITVBe reality show, Sam bid goodbye to TOWIE back in March 2014, after starring in eleven series.
Since leaving, Sam has gone on to embark on parenthood, recently becoming a mum to her baby boy Paul Tony Knightley. And as the seventeenth series of TOWIE prepares to hit out screens, Billie is hoping her sibling will make a comeback.
Speaking ahead of TOWIE's return, Billie said: "I shared most of my early TOWIE experience with Sam so definitely her. I think she should!"
We'd definitely love to have her back on our screens, and maybe little Paul could make a cameo? Just imagine those scenes with him and Billie's daughter Nelly - that would be pretty adorable, right?
Despite us wanting Sam to rub shoulders with our Essex faves once more, we're not so sure it is on the cards.
Back in November, Sam appeared to rule out a return to the show that made her a household name, insisting she has "come too far" to go back.
Sam said: "I'd never go back. I do still love the show, but I wouldn't go back now. I think when you come so far…I've come a long way since then."
